IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part of Letters Patent No. 158,549, dated January5, 1875; application filed November 28, 1874.

To all whom it may concern Be it known that I, PETER WARNER, of Gilead,in the county of Branch and State of Michigan, have invented a new andvaluable Improvement in Balance-Shoes for Thrashing- Machines; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a plan view of my device,and Figs. 2 and 3 are sectional views of the same.

This invention has relation to the shoes of thrashing-machines,clover-hullers, fanningmills, and other separators; and the nature of myinvention consists in a divided shoe, each section of which is supportedand guided by horizontal rods, and driven by means of a singlecrank-shaft, in such manner that they receive alternate reciprocatingmotions in opposite directions. for the purpose of balancing themotions, and thereby preventing vibration of said crank-shaft, as willbe understood from the following description.

In the annexed drawings, A designates the frame of a fanning-mill,thrashing-machine, or other like machine, which frame may be constructedin the usual well-known manner. B

desi'gnate slthe driving'shaft, which gives motion, to the two sections0 O, constituting the screening-shoe. The shoe-section O, with itsriddle a, is supported by means of horizontal rods b 11, extendingtransversely across the frame A, and to this section lateral motion isgiven by means of a crank, c, and a connecting-rod, e. The shoe-sectionG, with its inclined imperforated bottom f and laterallydischargingtrough g, is supported at its upper end by means of a guide-rod, b, andat its lower end by means of straps h h, which are pivoted,respectively, to the shoe-section U and to one of the sills of frame A.p This lower shoe-section Greceives lateral motion from the shaft B bymeans of a crank, 21, and a connecting-rod, j. The crank i is soarranged with respect to the crank c on the same shaft that theshoe-sections will run inopposite directions, thereby balancing theforces on shaft B, and preventing undue vibration of this shaft whenrunning the machine rapidly.

To prevent discharging any of the grain over the sides of the lowershoe-section, O, I make this section wider than the upper section, andapply to the inner sides and near the lower edges of this lower sectioninclined ledges k, which will direct the falling grain inwardly into theshoe (3.

WhatI claim as new, and desire to secure by Letters Patent, is

A shoe which is composed of sections 0 C, supported on rods 12 b, andreciprocated in opposite directions from crank-shaft B, as described,the upper section being provided with inclined ledges k, for the purposeset forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

PETER WARNER.
